Oil Pump testing.......

[midge]

the oil pump in my williams engine came loose, lost all oil pressure and started doing the b/e bearings, i shut it off as soon as noticed but it still ruined a bearing a 2. With mine i could hear it knocking right before i shut it off, not bearing knock but the pump knocking about in the engine.

willy or megane bottom end? Willy is shaft driven from the cambelt, megane is chain driven from the front of the crank. Everything is key'd so i'd think the only thing that could move would be the rod into the pump on the willy

Its a megan BE but not the latest one i think, has F7R cast in the back of the block.

Could the bolt of the pully that gives it drive come loose so its just spinning..?

Actually!! the sprocket on the crank is not key'd if there's no bolt tension the sprocket could spin. loose bolts holding the pump to the block are a possible,

i thought only the F7R 714 block was chain driven. all others are driven via the idler on the cam belt via the auxiliary shaft and rod into the oil pump.

iirc..

sounds like either a pump failure or spun bearing. but as there was no knocking i would go with pump/drive failure.

ive got a new oil pump sat in the shed if its any use if that turns out to be the problem

Dan ,you saying the megane block is not key,d so what stops it from spinning on the crank ?

[Evogone]

How do you test if the drive has gone or the pump has gone ?

Mine is a Megan BE but a 710 not the latest one which is the 714 i believe.
